More IPhone Suppliers

We can add National Semiconductor to this list now.

Infineon Technologies found its way into the iPhone with its digital
baseband, radio-frequency transceiver and power-management technologies, and National Semiconductor Corp. supplies the chip that connects the iPhone's
display to its graphics controller.

ISuppli said the touch-screen, considered to be one of the iPhone's
top selling points, is supplied by Epson, Sharp and Toshiba Matsushita, while
the display module is provided by German company Balda and its Chinese partner, TPK Holdings.

Balda is traded on the XetraDAX and TPK Holdings is 50% owned by Balda. It seems that Balda was pretty much a plastics injection modeling company from what I read. They seem to be branching out into a very technical field using this TPK Holdings expertise. I haven't read too many complaints about the touchscreen yet so this may be an interesting stock as well.
